King of snakes? (5)
I believe the answer is:
cobra
'king of snakes?' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for cobra that I've seen before include "a king, for example" , "One with hood" , "Venomous hooded snake" , "Poisonous snake" , "Venomous Asiatic and African elapid snake" .)
